., 3 Claims. (crime-32o This invention relates to roll window screens to be used in conjunction with windows wherein the roll screen is rotatably mounted below the window and within the sill or stool portion of the window frame. p,

The principal object of my invention is to provide a practicable roll screen for Windows that may be easily and quickly successfully installed in the frame portion of a window that would 'automatically compensate for slight dimensional variations in the window frame and one that does not require track means for the side margi nal edges of the screen when it is in effective operation. A still further object of this invention is to provide a roll screen of the in sill type that is so constructed as to resist dirt, water or other foreign and undesirable matter from passing into the roll screen compartment below the 'sill or stool portion of the window.

I A still further object of this invention is to provide a roll screen of the type designed to be detachably secured to the lower edge portion of a window that makes possible theproperand successful attaching of the window to the upper marginal edge portion of the screen when de' sired, A still further object of this invention is to provide a roll screen for Windows that may be easily and quickly installed regardless of the make, the type of weather stripping, or the balance of the window.

A still further object of this'invention'is' to provide a window screen that requires no additional rough framing at the time of installation.

A still further object of this invention is to provide a screen for windows of the roll type that rests under the window stool, forms the base of the stool and can be easily and quickly remove for repair or replacement. A e I A still further object of this invention is to provide a roll screen of the lower roll type that may be easily installed in new or old window frames and one that is so built that the stop for the screen wire is also the window stop. Y

A still further object of this invention is to provide a lower roll screen for windows that is so designed that its top molding is held closely adjacent the inside front of the moveable. glass window frame. V

A still further object of this inventionis to provide a screen for windows of the roll type that is so'constructed and assembled that ratchets, dogs and worm screws are eliminated: A still further objector this invention is to provide a roll screen that is economical in manufacture and durable in use.

These and other objects will be apparent to those skilled in the art. I

r My invention consists in the construction, arrangement and combination of the various parts of the device, whereby the objects contemplated are attained as hereinafter more fully set forth, pointed outin my claims .andillustrated in the accompanying drawings, in which:'

' Fig. 1 is an inside view of a window with my screen'installed thereon;

--"Fig. 2 is an enlarged cross sectional view of my installed screen with -the moveable window portion in closed position.

' Fig. 3 is aside View of the roller portion of the device.

Fig. 4 is 'a perspective view of the stool portion of the window sill. Fig. 5 is an end view of the roller holding bracket.

' "Fig. 6 is an end view of the upper and lower portionsof the screen.

' "The use of roll screens below the moveable portion of a window is old. The chief objections, however, to such types of screens is that they cannot be quickly and easily installed, require guides for the marginal edge portions of the screenwire; permit foreign matter to enter the compartment holding the roller mechanism, and are not constructed to automatically compensate for slight variations in the window frame structure. I have overcome such objections as will be appreciated and as will be hereinafter more fully set forth. 7

Referring to :the'drawings, I have used the numeral iii to generally designate a Window frame having the sill, I l, stool l2, and moveable window frame grooves i3 on each of its inner sides. The numeral vHI designates the lower 'moveable window having the usual frame por- "The numerals l8 and I1 designate two supporting brackets as shown in Fig. 3 and Fig. 5. In

the installing of the" device, the stool I2 is removed and the trim molding l8 on'each side of the window frame loosened or removed so that the upper end portion of these members l6 andv ll may be fastened by screws or like between'these two members and the main window frame H) as shown by dotted lines in Fig. 2.

By this construction a holding bracket will be detachably secured on each side of the lower portion of the window frame. These two bracket members have their center portions bent laterally outwardly and then downwardly to provide a shoulder IS. The numeral 20 designates a housing shield engaging these two shoulders I9 and secured to the same by any suitable means such as soldering, spot welding, screws or like. Substantially all stools |2 are out of the same design, and the under portion of the stool engages and rests upon the central portion of this shield 20 after the stool is replaced as shown in Fig. 2. The forward marginal edge of the shield 20 embraces the front marginal edge of the stool 2 and extends upwardly and rearwardly to a plane a slight distance above the forward marginal edge of the stool as shown in Fig. 4. This prevents needles, pins or like material laid on the stool from falling over the forward edge of the stool and entering the compartment holding the roll screen. The rear end portion of the shield 20 extends downwardly to engage the usual detachable back board 2| as shown in Fig. 2. The numeral 22 designates a slot opening in the lower portion of each of the bracket members l6 and H a shown in Fig. 5. The numeral 23 designates ear member on the outer side of each of the bracket members, The numeral 24 designates a rod having flattened ends and extending between the two bracket members and resting in the slot openings'22 of each of the brackets. The numeralv 25 designates a pin, cotter key or like extending through each pair of ears 23 and through one end of the rod 24 for holding the rod 24 in place and against rotation relative to the bracket members. The numeral 26clesignates a hollow roller rotatably mounted around the rod 24 and positioned between the two holding brackets. This roller 26 has a longitudinal slot opening 21. The numeral 28 designates a coil spring embracing th rod 24 and inside the hollow roller 26 with one end rigidly secured to. the rod.24. and its other end hooked to engage a notch 29 in the marginal edge ofthe slot 21 of th roller. By this arrangement, the roller 24 will .be yieldingly held in one direction of its rotation. The numeral 30 designates a metallic resilient weather strip secured'to the top rear portion of the sill and extending rearwardly and upwardly to a line closely adjacent the front wall of the shield 20 as shown in Fig. 2. The numeral 3| designates an elongated screen mesh having a hooked flange 32 on its lower inner marginal end. This metallic hooked flange is rigidly secured to this end o e screen mesh and extends into the slot opening 21 of the roller, thereby holding the lower inner end of the screen mesh detachably to the roller 26. The length of the screen mesh is wound around the roller 26 and is yieldingly so held by the coiled spring 28. The free end of the screen mesh extends upwardly between the forward wall of the shield 20 and the rear marginal edge of the weather strip 30. On this upper end of the screen mesh is a metallic hook flange 33. This member 33 embraces. the upper marginal edge of the screen mesh and is rigidly secured to the same by crimping, solder or like. While the member 32 is similar to the member 33, the member 32 is hooked in the opposite direction from the member 32v as shown in .Fig. 6. Th member 33 extends forwardly and inwardly in a curved path. and has. on its rear base forward portion a flange 34 which extends forwardly and downwardly. This elongated flange 34 serves at least two purposes, i. e., it engages the top of the inwardly and upwardly extending weather stripping 30, thereby sealing the same and further forcing the free end of th weather strip toward the shield 30 and against the screen mesh to completely and efliciently seal the compartment 35 which contains the roller mechanism. The hooked flanges 32 and 33 extend the complete width of the screen mesh. The nu; meral 36 designates two spaced apart pick-up fingers on the rear side of the lower portion of the moveable window. These fingers have their lower ends hooked to detachably engage the hooked flange 33 of the screen mesh, as the member 33 extends the width of the window. These pick-up catch fingers are always in position to engage and hold the free end of the screen to the moveable window, thereby automatically compensating for any minor variations in window frame construction. Th numeral 31 designates a handle portion on each of the members 36 and as the members 36 are pivotally secured to the moveable window portion, the downward pressing of the portions 31 will move the pickup fingers out of engagement with the flange hook 33 and the window may be raised or lowered Without lowering and raising the roll frame. When it is desired to pick up the screen mesh so that it will fa11 upwardly with the window as shown in Fig. l, the portions 31 are manually moved upwardly to bring the hooked pickup fingers under the hooked flange 33 as shown in Fig. 2. The screen mesh due to the construction of the fingers and member 33 is held closely adjacent the lower rear side of the moveable window portion. This means not only a tight fit of the screen relative to the moveable window portion but also that the marginal side edges of the screen will lay against the side Wall of one of the window grooves I3 as it extends upwardly in operative condition. By this structure, guides or like tracks for holding the marginal edges of the screen mesh are unnecessary.

In repairing or replacing the screen or its roller mechanism, it is merely necessary to remove the backboard 2|. For installation, the stool |2 may be removed. When the stool and member 2| are replaced, it will be noted that the entire screen that is in lowered condition and the roller mechanism and supports therefore, are under the stool 2 and to the rear of the sill When the window is open and the screen is in operative position, the Weather strip 30 and forward wall of the shield 20 will be closely adjacent the two sides of the screen mesh, thereby preventing water, flies or foreign matter from successfully entering the compartment 35.

To remove the roller mechanism and screen wire wound on the same, it is merely necessary to remove the cotter keys or like 25.

Some changes may be made in the construction and arrangement of my improved window screen without departing from the real spirit and purpose of my invention, and it is my intention to cover by my claims any modified form 'of structureor use'of mechanical equivalents which may be reasonably included within theiriscope.

I claim:
